Multiple security vulnerabilities have been identified in the Hewlett-Packard Linux Imaging and Printing Project (HPLIP) packages included with Red Hat Enterprise Linux (RHEL) versions 8 and 9. These vulnerabilities include privilege escalation and arbitrary code execution via operating system command injection and integer overflow in the hpcups component. Red Hat has released security updates addressing these issues for various architectures and extended support versions of RHEL 8 and 9.

The opencryptoki packages contain version 2.11 of the PKCS#11 API, implemented for IBM Cryptocards, such as IBM 4764 and 4765 crypto cards. These packages includes support for the IBM 4758 Cryptographic CoProcessor (with the PKCS#11 firmware loaded), the IBM eServer Cryptographic Accelerator (FC 4960 on IBM eServer System p), the IBM Crypto Express2 (FC 0863 or FC 0870 on IBM System z), and the IBM CP Assist for Cryptographic Function (FC 3863 on IBM System z). The opencryptoki packages also bring a software token implementation that can be used without any cryptographic hardware. These packages contain the Slot Daemon (pkcsslotd) and general utilities. Security Fix(es): * openCryptoki: openCryptoki: Privilege Escalation or Data Exposure via Symlink Following (CVE-2026-23893) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A timing side-channel vulnerability (CVE-2024-0914) exists in the opencryptoki packages used by Red Hat Enterprise Linux 8.6 Extended Update Support. The flaw affects the handling of RSA PKCS#1 v1.5 padded ciphertexts, potentially leaking sensitive information through timing differences. The issue is rated as moderate severity by Red Hat. A security update addressing this vulnerability is available for affected packages.
